MA-AD8 Digital Mic Amplifier

TASCAM MA-AD8
B
DIGITAL I/O1 (FROM MIC INPUTS)
This connector is typically used to connect a TDIF-1-
equipped mixing console.
The digital audio signals received at this connector
will always be passed through to the
DIGITAL I/O2
(AUX)
w
connector. This cannot be changed.
The digital audio signals output from this connector
are selected from either the MA-AD8 A/D converters
or from the signals received at the
DIGITAL I/O2
(AUX)
w
connector, depending on the settings of the
INPUT
switches
5
.
WARNING
Note that you should always use genuine TAS-
CAM cables, or cables which have been
approved for use with TDIF-1 interfaces by
TASCAM.
Although these cables appear similar to certain
types of computer cables and use similar con-
nectors, the cables themselves are very differ-
ent, and the different electrical characteristics
of the cables can cause damage to the equip-
ment connected with the wrong cables.
If the use of cables other than TASCAM cables
causes or results in damage, the warranty is
voided.
C
DIGITAL I/O2 (AUX)
This connector is typically used to connect a TDIF-1-
equipped multitrack recorder, such as a DTRS
recorder.
The digital audio signals output from this connector
will always be the digital audio signals received from
the
DIGITAL I/O1 (FROM MIC INPUTS)
q
con-
nector. This cannot be changed.
The digital audio signals received at this connector
may be used as sources for the
DIGITAL I/O1 (FROM
MIC INPUTS)
q
connector, depending on the setting
of the
INPUT
switches
5
.
D
WORD IN
An external word clock may be connected to this BNC
connector (75
Ω
), and used as the word synchroniza-
tion for the MA-AD8, selected with the
CLOCK
switch
3
.
E
WORD THRU
This BNC connector echoes the clock signal received
at the
WORD IN
e
connector. If no device is con-
nected here, the word clock chain is automatically ter-
minated.
1.3 A practical example of using
the MA-AD8
Since the MA-AD8 provides a good deal of flexibility,
it may be useful to review a typical situation in which
it may be used.
1.3.1 Recording multitrack tracks
In a multitrack situation, the initial tracks may be laid
down using the following setup:
In this example, all the
INPUT
switches
5
on the
MA-AD8 are set to accept signals from the internal A/
D convertors (i.e. from the
MIC
sources)
➀
. The signal
then goes from the
DIGITAL I/O1
port into the mixer
➁
, which can now use channels 9 through 16 as addi-
tional inputs from analog sources. The group busses
are routed back through the TDIF-1 connector
➂
and
are passed through the MA-AD8’s
DIGITAL I/O2
connector to the DTRS recorder
➃
.
The word clock originates in the TM-D1000, and the
CLOCK
switch on the MA-AD8 is therefore set to
TDIF-1
, and the
STATUS
switch to
D I/O1
. This
clock is passed through the TDIF-1 connection to the
DTRS recorder.
1.3.2 Mixdown
When mixing down, the situation is simplified as
shown below:.
The
INPUT
switches
5
of the MA-AD8 are set to the
TDIF-1
setting and the tape tracks are replayed into
